London has a new magazine. But it is not printed(印刷) on paper. Everyone who has a television can receive it because it is on TV.

In order to read this magazine you have to have a decoder (解码器). Each page of it is numbered, so you only have to dial the number to choose which subject you want to read about. There are all kinds of information ---everything is included from cooking to the latest sports news.

If you want to read the news, the first thing you have to do is to turn to the back page, which has an easy-to-remember page number, 100 for example. Then you start choosing what you want to read. The news is on page 101 to 109, so you put in the numbers and the news appears written across your screen. Perhaps you want to go out in the afternoon, so you press 181, and a brightly colored weather map appears on the screen. But the weather is terrible, so you decide to go shopping and dial 162 for a list of the week’s best bargains. But should you drive or take the train? To answer that question you only have to press 189 for the traffic report. It is very simple to use. But probably the best thing about the service is that it is being updated all the time. Journalists type new material directly onto the screen and the whole pages of the magazine can be replaced in minutes.

London already has three services. One, sent out by TV, is called ORACLE while the other two, on BBC, are called CEEFAX because they let you see facts. Although CEEFAX and ORACLE have been operating for some time, they have not been well publicized(宣传). BBC engineers do not think that their idea will ever replace books and newspapers because they can be taken with you everywhere. But many people would agree that is a breakthrough(突破) as great as the invention of printing, which could not just change our reading habits but our whole way of life.

Not long ago, the only time you could see a robot was when you were reading a novel or watching a movie such as Star Wars (星球大战) . Today, however, a lot of things in science stories have been science facts. Robots are starting to appear in our everyday lives. These robots have different sizes, shapes, and colors. But they all have the same type of man-made “brain”. Leading the robot revolution (革命)are industrial(企业) robots that work in factories. Industrial(工业) robots can do different kinds of jobs that are often boring and sometimes dangerous. Robots are also coming to American homes, though not as quickly as they are entering factories. These robots aren’t as friendly and bright as those you saw in  Star Wars. But, their makers say, today’s home robots “walk”, sense objects(感知物体) in their way (and sometimes knock into them), and even carry objects (which they sometimes drop). Well, nobody is perfect.
We may laugh at home robot today, but some day they may see and hear better than humans do. We humans can only see certain wavelengths(波长) of light, and hear certain sounds. That’s because the abilities of our eyes and ears are limited. Robots, however, need not have the same limits as we have. Robot may also be equipped with devices that pick up information humans can’t. To understand what their sensing devices(传感器) pick up is a hard job. Remember, man—made brains handle(处理)information, including all kinds of data, as zeroes and ones. Imagine the difficulty in trying to explain to a robot what a football looks like—using only zeroes and ones.
